A feature is needed that allows the DualSense touchpad to be recognized as a laptop touchpad at the driver level, treating it as an actual device.
Some game security features designed to prevent hacking tools disable software-level mouse functionality.
Even if full driver-level integration is not possible, it would be great if it at least worked like Microsoft's Mouse without Borders, so that it isn’t blocked by game security tools.
For reference, the game I play is Mabinogi Mobile.
